MAX6367PKA29/V+T

Overview

The MAX6367PKA29/V+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.65 V to 5.5 V and features a fixed threshold voltage of 2.9 V for monitoring input lines. The device provides an active-high, open-drain reset output with a typical reset delay time of 280 ms. Designed for battery backup applications, it includes a chip-enable gating function to minimize power consumption during standby modes. The component is housed in an SOT-23-8 package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates battery backup switching functionality to maintain system state during power transitions.
• Features chip-enable gating capability to reduce quiescent current consumption when the system is inactive.
• Provides a dedicated reset output signal that activates upon detection of undervoltage conditions.

Applications

• Battery-powered portable electronic devices requiring reliable power management.
• Embedded systems utilizing microprocessors or microcontrollers needing supervised power rails.
• Industrial control units operating within extended temperature environments.

Procurement Notes

Verify the specific suffix 'V' against the manufacturer's official datasheet to confirm environmental compliance and packaging specifications. Confirm availability status through authorized distributors as this part may be subject to limited supply or end-of-life constraints. Ensure the selected variant matches the required threshold voltage and output configuration for your specific application design.

Selection Notes

Select this component when a fixed 2.9 V supervision threshold is required for single-input monitoring. Consider the active-high open-drain output compatibility with your system logic levels. Evaluate the need for chip-enable functionality to optimize power efficiency in battery-operated designs. Compare against other series members if different threshold voltages or reset delays are necessary.

Part Context

This part belongs to the MAX6367P series of low-power supervisors from Maxim Integrated. It shares architectural similarities with other parts in the family but differs in specific threshold settings and output configurations. The series is designed for applications demanding minimal current consumption while providing robust reset generation for sensitive digital circuits.

Replacement Considerations

Direct substitutes include other MAX6367 variants with matching 2.9 V thresholds and compatible pinouts. Verify functional equivalence regarding reset delay times and enable logic before substitution. Cross-reference with MAX6366 or MAX6363 series parts only if watchdog or manual reset features are not required.
